I don't believe in time-lines or even in linear time.

I don't agree that anything I can imagine must exist somewhere. That strikes me as egocentric, though that is my impression and it may not be that way for others. I don't like how arrogant our species is, we think we are the center of the universe and existence! So many of us espouse a concept of a final cause or purpose, which inevitably centers upon human existence and some concept of becoming, attaining or improving. We have psychological reasons for thinking this way, but I think we are an incredibly ignorant and naive species that is looking to justify our existence by saying that there is an ultimate reason or purpose for it. However there are a lot of problems with this. It is like we see a shape in a cloud and insist that the cloud is that shape on purpose. Then if someone else sees a different shape than we did, we tell them they are wrong...

I don't even believe in hyperspace as a dimension, for me it is a dose dependent effect, not a location. I've seen a great many people use DMT and breakthrough but still be there, often speaking or mumbling incoherently, it is clear that their consciousness has not separated from their body. Though perhaps they are tuning into something, though I do not believe this is the case, I think it is more akin to a signal flange or phase shift than anything else.
